**Annual Operating and Maintenance Costs for the Juneau 48.3 MT/day By-Products Recovery Plant**

**Item Description**  Operators 3 persons per shift in salmon season & two shifts/day manager 1 person per day laborers 2 persons X 4hr/day Diesel Fuel Diesel Fuel for Boilers @ 44.4 gal/hr Electrical kW for 25 MT/day plant scaled to 48.3 MT/day Chemicals Boiler chemicals and CIP chemicals are $3.25/1,000 gal Maintenance Equipment Replacement parts and equipment is 1% of Direct Cost Product Shipping **Notes:** Salmon season assumes operating 24 hrs/day. Non-salmon season assums operating 8 hours per day. Operation requires 3 persons per shift per Rick Eaglin Electrical requirements for the 25 MT/day by-products plant is 233.4 kW from Rick Eaglin Diesel fuel requirements for the 25 MT/day 200 BHP boiler at 60% efficiency is 23 gal/hr from Cleaver Brooks. Fuel for other size plants scaled directly to MT Maintenance equipment is based on Perry's Chemical Engineers Handbook that states maintenance ranges between 2 and 6% of direct capital, but 1/2 is labor. This cost assumes light manufacturing so 2% of capital, and no incremental maintenance labor since operator will perform maintenance. Boiler and chemical costs at $3.25/1,000 gallons of water to boilers. The 25 MT/hr plant requires 1,900 lbs/hr steam. Assume blowdown is 6% of steam. Boiler chemical cost of $3.25/1,000 gallons of water from Kadant Boiler Feed Pump Document on Liqui-Mover Pump**Annual Operating and Maintenance Costs for the Juneau 48.3 MT/day By-Products Recovery Plant**
